Western blot analysis of antigenic recognition patterns of dog serum. Representative individual dog serums (Lanes 1–21) were tested for T. cruzi protein recognition. Positive (+) or negative (−) reactivity is indicated at the bottom of each lane. Note that some dogs showed a very similar band recognition pattern (Lanes 5–8 and 10), but serum from most seropositive dogs recognized widely different parasite antigen patterns (Lanes 12, 14 and 16–21)
